A quick clarification about the video: The photodiode we’re using approximates the spectral response of the human eye, meaning it can detect visible light better than other photodiodes. This is exciting, since you can send secret messages from a typical LED of any color and OpticSpy will be able to see it! It is quite sensitive to infrared (IR), as well, allowing us to support a wide range of wavelengths.

As the campaign comes to an end, I’m starting to prepare for production. Our manufacturer, e-Teknet, is ready to go and my component shopping carts are loaded. I’ll update the final quantities over the weekend and place the orders on Monday.
